Guest Additions, should we be concerned about version differences?

I found an Intel based Mac and got by #510. Then I got it with #506. Now I'm getting the following errors. If guest additions matter, suggestions on how properly configure them? (or avoid them all together if that's my problem.)

Except for adding `virtualbox__intnet: true` to the end of each private network config line, I've only copied and pasted the Vagrantfile code from Ch3.

```
